In many ways it’s a pity more games didn’t come out like this. Using careful pallet swaps to keep the game speed up, and utilising the plus ranges features to excellent effect. Although I suspect there was just very efficient coding at play.
If fact I can say the same with the audio, while no tune is truly memorable, they are catchy, and the effects noises are such that they never overstay their welcome in a session.
And did I mention this isn’t just a single player game… there’s co-op too which adds a whole new dynamic just through co-ordinating strategy and attacks.
Overall a belter of a game and one every retro gamer should try!
